But Facebook's director of artificial intelligence research, Yann LeCun, is not convinced. Tweeting out Business Insider's December interview with Sophia, LeCun wrote: "This is to AI as prestidigitation [conjuring tricks] is to real magic. Perhaps we should call this 'Cargo Cult AI' or 'Potemkin AI' or 'Wizard-of-Oz AI'. In other words, it's complete bullsh*t (pardon my French)."

He concluded: "Tech Insider: you are complicit in this scam." Ouch.

LeCun didn't respond to Business Insider's request for elaboration but his criticism appears to be that Sophia, which can talk to humans in a conversational manner, isn't human-level artificial intelligence or even close. Instead, it's more like a chatbot, with no understanding of what it's doing.

Ben Goertzel, CEO and chief scientist at SingularityNET, said he had never pretended Sophia was close to human-level intelligence. Sophia was created by a separate firm, Hanson Robotics, and is now the robot face of SingularityNET.

He said the robot was a piece of human-looking hardware which ran different programmes under different circumstances. For example, when Sophia is talking to a journalist, it's running software that turns it into a "sophisticated chatbot." When it's giving a speech at the United Nations, it's running off a pre-programmed script. Sometimes it runs on Goertzel's OpenCog AI software system.

And Goertzel had some sharp words for Facebook and Yann LeCun too.

"Obviously I don't agree with his statements," Goertzel told Business Insider. "I find it kind of funny. Like Facebook is obviously gathering everyone's personal data and then using machine learning to post Russian-generated fake news onto everyone's Facebook page to make them vote for Donald Trump. After using machine learning this way to manipulate people's minds, Facebook wants to take on a startup for making a loveable robot."

This is something of an exaggeration — Facebook estimated that 150 million Americans saw misinformation relating to the US election. It's a substantial amount, but not "everyone," and it's a stretch to say this forced anyone to vote for Donald Trump.

Goertzel acknowledged Sophia isn't artificial general intelligence, the industry term for human-level machine intelligence, and said no one's achieved this yet.

"The current software controlling Sophia is not human-level general intelligence, but neither is anything Facebook is doing, nor is anything Google is doing," he said. "What's a bit outrageous to me in comments like Yann LeCun's is that it's exalting certain forms of narrow AI and saying the kinds of narrow AI he is doing at Facebook is 'real AI', and the kinds of narrow AI underlying Sophia is not real AI. That's bullshit."

This, combined with Sophia's ongoing media coverage, explains the criticism. But Goertzel thinks other AI organisations are jealous of the public attention — and says it's good normal people are debating and talking about artificial intelligence.

"I think the negative reactions are from jealous people in AI or the tech world saying, 'Why aren't people paying attention to our tech?'" he said.

"Most people don't care," he added. "Even if you tell them she doesn't understand, people want to relate to her as a character anyway."
